Abstract (en)
[origin: US5461015A] A porcelain having 9 to 55% by weight of SiO2, 36 to 87% by weight of Al2O3, 0 to 2.0% by weight of Fe2O3, 0 to 1.0% by weight of TiO2, 0 to 0.5% by weight of CaO, 0 to 0.5% by weight of MgO, 1.0 to 4.0% by weight of K2O and Na2O combined, and 0.25 to 25.0% by weight of bismuth oxide is disclosed. The porcelain has unexpectedly high unglazed bending strength and may be used for dielectric and structural applications.
